Health Secretary Robert F. Kennedy Jr.'s intervention in COVID-19 vaccine recommendations without input from a key U.S. CDC advisory panel has sown confusion among physicians and insurers over who should get the shots and whether they will be covered,

A medical officer at the US Centers for Disease Control and Prevention who was working on the committee that was weighing changes to the agency’s Covid-19 vaccine recommendations resigned on Friday, the same day officials the US Department of Health and Human Services announced they had removed the CDC recommendation for pregnant women and healthy children to get Covid-19 vaccines.

Lakshmi Panagiotakopoulos said she could no longer help vulnerable people after officials removed recommendations to immunize children and pregnant women.
